Description

TECHNICAL FIELD

[0001] The invention disclosed herein relates generally to a fenestration assembly and more specifically to achieving low thermal conductance across a fenestration assembly.BACKGROUND OF THE INVENTION

[0002] Curtain walls, building facades, store fronts, windows, glazed doors, decorative and utility glazing and the like, generally known as fenestration products, are typically made with aluminum framework. Aluminum is favored because of its light weight combined with good strength and extrudability. The fenestration art has struggled, however, with the relatively high thermal conductivity of aluminum, which tends to reduce thermal efficiency in all climates.

[0003] One widely accepted solution to the thermal conductivity problem has been to introduce one or more members having low thermal conductivity between internal and external aluminum parts; often the inserted member is made of a synthetic polymer having a low thermal conductance. For example, glass fiber reinforced po...
